[PATCH] RISC-V: Make NUMA depend on SMP

From: Palmer Dabbelt <palmerdabbelt at google.com>

In theory these are orthogonal, but in practice all NUMA systems are
SMP.  NUMA && !SMP doesn't build, everyone else is coupling them, and I
don't really see any value in supporting that configuration.

Fixes: 4f0e8eef772e ("riscv: Add numa support for riscv64 platform")
